Transcriptomic dynamics and cell-to-cell communication during the transition of prospermatogonia to spermatogonia revealed at single-cell resolution by Zhen He, Rong-Ge Yan, Qin-Bang Shang, Qi-En Yang

“…Abstract Background Spermatogonia are essential for the continual production of sperm and regeneration of the entire spermatogenic lineage after injury. In mammals, spermatogonia are formed in the neonatal testis from prospermatogonia (also termed gonocytes), which are established from primordial germ cells during fetal development. …”

Mice with NOP2/sun RNA methyltransferase 5 deficiency die before reaching puberty due to fatal kidney damage by Hongya Zhang, Xiaohui Li, Jing Bai, Cong Zhang

“…However, our knowledge of the biological functions of NSUN5 in mammals is very limited. Therefore, in this study, we investigate the role of NSUN5 in mice.Methods In the present research, we built a mouse model (Nsun5-/-) using the CRISPR/Cas9 system to investigated the specific role of NSUN5.Results We observed that Nsun5-/- mice had a reduced body weight compared to wild-type mice. …”

Archaeozoological material from the Late Antique fortified settlement near the modern-day town of Dimovo, northwestern Bulgaria by Zlatozar Boev, Alexander Manev, Alexander Harizanov, Ivaylo Dedov

“…Along with animal husbandry, hunting still had a significant place. Some wild mammals (such as wild boar, Еuropean hare, red deer, roe deer, fallow deer, aurochs, and European bison) were hunted for food, while others (such as red fox, wild cat, grey wolf, brown bear, and beaver) were hunted for their fur. …”

Zebrafish Fins as a Model System for Skeletal Human Studies by Manuel Marí-Beffa, Jesús A. Santamaría, Carmen Murciano, Leonor Santos-Ruiz, José A. Andrades, Enrique Guerado, José Becerra

“…Recent studies on the morphogenesis of the fins of Danio rerio (zebrafish) during development and regeneration suggest that a number of inductive signals involved in the process are similar to some of those that affect bone and cartilage differentiation in mammals and humans. Akimenko et al. (2002) has shown that bone morphogenetic protein-2b (BMP2b) is involved in the induction of dermal bone differentiation during fin regeneration. …”
